The particular object of the invention use in removing transmission bands from a transmission case having means for receivinto the transmission case. i 7

Other objects of the invention will. appear from the following description and the accompanying drawings and will be polnted out in the annexed claims. o 1 V In the drawings, therehas been disclosed a structure designedto carry out the various objects Of the invention, but it is to be um topermit the vremoval :of th'ebands from the whenpressu're is brought'to bear upont-he and thus causing the tovmaveaway from: thenutso that itwxnay readily be rotated 1' upon the pedal shaft withontthe use -of a,

The shank 13 of the tool is prefer- 7 mission case will provide a pivotal point upon which the tool may oscillate, asj rjidi Gated by the dotted linesin Figure 3. When the ted-is moved; from the an ts the dotted lines position in this ugure, the lower open end of the receptacle (3 will engage the upright lug; 9 of the band and will force it i11- wardly or towards the relatively stationary lug l7, thereby ren'ioving the pressure against the adjusting nut so that it may be readily rotated upon its shaft without the use of a wrench or other tool.

By the use of this novel tool. the adjusting nuts and lock-washers oi the transmission bands may readily be removed from the pedal shaft without the use of a wrench or other tool and without any danger of such parts accidentally dropping into the lower port-ion of the transmission ease. \Vhen the adjusting nut is removed :trom the end oi the pedal shaft, it will drop into the cup shaped end-portion ot the tool as indicated by the dotted lines in Figure after which the pedal shaftmay be partially withdrawn from the transmission case and the tool removed therefrom carrying with it the adjusting nut and lock washer.

This novel tool may also be used when adjusting the bands to take up wear. lVhen thus used the tool will be inserted into the case as shown in Figures 9 and 3 atter which pressure will be brought to bear against the handle 16 to compress the band; After the band has thus been compressed the adjusting nut 11 may readily be re tated upon its shaft to relatively adjust it e position of the band.

Having thus described our invention, what we claim as new and desire to secure by United States Letters Patent, is:

1. A tool of the class described, coinpris ing a shank having a receptacle terminally formed thereon the bottom of which is a rranged at substantially right angles to the axis oi the shank; there being an offset. on the shank adjacent said receptacle to permit the insertion of the receptacle into a transmission case and to position it in engagement with a transmission band, and with the shank engaging a portion of the transmission case to provide a fulcrum for the tool, whereby the transmission hand may be compressed and its adjusting nut rcmoved therefrom and received in said. receptacle.

2. A tool of the class described, comprising a shank having a receptacle terminally termed thereon and open atone end and having its bottom ar 'anged at substantiall right angles to the axis of the shank, there being an otl'set in said shank adjacent said. receptacle to permit the insertion of the receptacle into a transmission case with its open end in engagement with a transn'iission band beneath the adjusting; nut and lock washer thereof, the offset in said shank being so shaped that when the receptacle is in engagement with the band, the shank will engage a portion of the transmission case to provide a fulcrum for the tool, whereby the band mav be compressed to permit the re moval of the adjusting nut therefrom.

3. As anew article of manufacture, a tool comprising a shank having an elongated receptacle thereon having its top and onecnd open, there being an ofiset in said shank whereby the receptacle may be inserted into a transmission case with its open. end engaging a transmission band, the open end of the receptacle being offset from the axis of the shank whereby, when said end is engaged with the band, and the tool is operated to compress said band, the nut may be removed from its supporting means and will be received in the receptacle for rcmoval. from the transmission case. i

4-. A device of the class described co1nprising a shank having a portion thereof otl'set from the axis of the shank and arrangedv substantially parallelthereto, a receptacle integrally formed with said o'ttset portion and havinp; its hottoinarranged at substantially right angles to the axis ot the shank, said receptacle having its top and one end open, and the open end of the receptacle being adapted to engage a transmission band. as the shank fulcrums on the transmission case.

In witness whereof, we have hereunto set our hands this flith day (it July 1925.
